What Causes Sinus Arrhythmia At Leftward Axis?

I felt ill at a football gameyesterday and had an ECG at the stadium, It read Borderline ECG "Unconfirmed" Sinus arythmia Leftward Axis

A few minutes later they did a second one Same text otherwise except it said Sinus rythym. 10 years ago I saw a specialist who said it was hardening of left ventricular wall. Is this serious. Can I do anything? I am 62 5feet 9inches and 12.5 stones. No health problems otherwise.

Hello,

No it's not a matter of worry. Normally those who are engaged in heavy activities like sports tend to increase in thickening of heart wall in order to compensate for heavy activities. And this thickness is mainly on left side, which ECG reads as left axis deviation. Also, sinus arrhythmia is normal phenomenon and it basically a change in heart rate with respiration. So normal. If you still have some doubts you can get echocardiography done.

Hope I have answered your query. Let me know if I can assist you further.

Regards,
